hwey guys, i'm trying to build a cool little hardware synth out of the 556 dual timer. have you seen anybody do something like this with a 555 equivalent? and so i drew out these schematics, modified from some site and i'm wondering if any of you know if this might work...or if i did something wrong, or could make it easier for myself. basically, you have a switch to choose the octave, with diff. resistors, and then when you hit a key, it adds resistance to the octave "base" resistance, so i'm pretty sure i actually dont need R1, since the octave and key area actually R1. but will that screw with something? i think the difference between R1 and R2 determines the pulse width or w/e, and it'd be nice to have a switch to control that. and i havent done all the math, so yeah...thyanks
it'll be like monomate, but hardware

edit: eep! wrong forum! i just saw that there is actually a DIY synth section...ummm feel free to move this there.

i think the best way to develop things is by breadboarding them. so you can try if the R1 is necessary and you can tweak other component values . when you are pleased whit what you have, just solder everything up on a stripboard or veroboard

yeah, i havent really ordered all the components yet so i was just fleshing out some ideas, so i'll probably buy a breadboard now, seeing as how they work, instead of alligator clipping everything together..and yeah, sorry about the ridiculously sloppy diagram.
